Selecting ObjectProperties is not working in the OEO Viewer and OEO entity details pages

[jh-RLI]

Description of the issue

When one wants to inspect a ObjectProperty (not tested for all availabe) then the new TSS-Widgets state that there is no information available. Other properties work.

Steps to Reproduce

1. E.g. Go to https://openenergyplatform.org/ontology/oeo/BFO_0000050/
2. Click on the property tab (top right)
3. No info is loaded
4. Click on "Explore this term in the OEO Viewer"
5. No info is loaded

Ideas of solution

No idea currently. Contected the TSS widget devlopers if they have an idea.

Possible that there is a bug in the OLS System or in the current OEP integration setup.
